This section guides you through the process of building the structural framework of your model — the flow network.
You will learn how to represent real-world components of a hydrological system — such as rivers, reservoirs, and catchments — using the model’s system elements: Transport Reaches, Storage Elements, and Sub-Basins.
These elements are then connected to form a flow network, which mirrors the pathways water takes through the system — whether naturally through terrain and rivers, or via human-made structures like canals and dams.
Later chapters will cover how to configure these elements, assign input data, define operating rules, and ultimately run and calibrate your model. Here, we focus on laying the groundwork: building the network that everything else depends on.
